Did you know that each day one person in the US throws away 4.4 pounds of rubbish? Almost every month，we throw away our own rubbish in packaging alone．Packaging（including boxes，bags，etc）comes to our homes with the things we have bought．Several weeks ago，the TV news said that in a city in Italy tons of rubbish were piled up in the streets，and the smell was rather terrible．What can we do to help? We should get to know the following Rs．

Reduce   To reduce means to make less rubbish．That is one of the first things we all should do for the environment．Reduce your rubbish by doing things like packing your lunch in reusable containers（可再利用的容器），taking smaller potions（份）at dinner so you don't waste food when you have had enough，writing on both sides of paper，and using less water when taking a shower．

Reuse      To reuse is to use things again．Think about the bags you get from the store．They can be reused to carry your lunch，to hold your rubbish，or to collect used cans．You can even take them back to the store the next time to carry your things instead of getting a new bag!

Recycle（回收利用）  Recycling is an important part of keeping our planet clean and green．It can also save energy．Be sure that you don't throw things in the rubbish that can be recycled to make something else．Paper，plastic，cans and bottles can all be recycled，but food，electrical waste and mobile phones can't．When you are not sure whether something can be recycled，go to your parents and teachers for advice．

Follow the three Rs，and every one of us can do something to save the earth．It is also the best way to save ourselves．

1．The first paragraph of the passage implies（暗示）that                     ．

A．packaging should be given up                       B．Italy is too dirty for us to visit

C．the US produces most rubbish                            D．the earth is becoming dirtier

2．If you want to reduce，you should                ．

A．make good use of your paper                       B．take a bath instead of a shower

C．eat a small dinner every day                         D．pack your lunch with newspapers

3．The writer seems to ask people to reuse the bags                 ．

A．only as rubbish bags                                          B．only for carrying other things

C．mainly to have a cleaner world                     D．mainly to save some money

4．Which of the following can be recycled?

A．Food and bottles．                                  B．Books and newspapers．

C．Paper and mobile phones．                          D．Plastic and electrical waste．

5．The passage mainly tells us that                   ．

閱讀下面的短文，并完成短文后的任務。

Draw a giraffe in your mind. How did you draw your giraffe? Does it have a long neck? Does it have long legs? Is it really tall? When people think of giraffes, they think of their long necks. A long neck and four long legs make the giraffe the tallest land animal on earth. A giraffe is 1.8m tall when it is born, and some giraffes get up to 6m tall when they are all grown up.
But did you know that giraffes also have long tongues? Have you seen the tongue of a giraffe before? A giraffe has a very long tongue which can hold and wrap (包) around objects. The tongue is designed for feeding, but it can be used in many different ways. For example, a giraffe can close its nose with its long tongue completely to keep out sand and dust. Also, a giraffe’s tongue is long enough to clean its owner’s ears as well!
The tongue is black in colour to protect it from getting sunburnt (曬傷). It is nearly 56cm long. Giraffe only eat plants, and a full grown giraffe can eat 33kg of leaves a day. When giraffes look for some tall trees to eat, they sometimes fight with elephants for food. Giraffes use their tongue to eat leaves from some tall trees. The giraffe’s tongue is a helpful tool for reaching leaves and breaking off branches.
